TO MAKE INTO BREAO-TO TURN INTO MEAT AND MILK Get better yields by keeping soil moist and warm CULTIVATE TO STORE MOISTURE Cultivate as soon after rains as the soil has dried sufficiently. Keep the soil surface well stirred and light. This will let rain soak in quickly and reduce waste. In fair weather it will prevent the subsoil from drying out. A well-stirred surface soil will send mois- ture, laden with plant food, up through the corn roots and stalks to make ears. CULTIVATE TO DESTROY WEEDS Every weed in a cornfield is an enemy. Weeds drink up moisture and consume plant food that should go to make corn kernels instead of weed seeds. Destroy your weed enemies when they begin to appear. Don't wait for them to mobilize in strength. Attack weeds if possible in fair weather. You will then have the sun as a powerful ally. CULTIVATE TO WARM THE SOIL Evaporation of moisture lowers tempera- ture. A wet, evaporating soil surface, therefore, is cold. A dry soil surface is warm. A loose soil surface dries quickly. The blanket of loose, dry soil then stops further evaporation. It drinks in sunshine and be- comes warm. In northern localities and at high altitudes the warming of the soil frequently is as im- portant as conservation of moisture. PUT PRODUCTION Of FOOD CROPS FIRST WATCH YOUR SOIL The condition of your soil should determine when to cultivate. Cultivation by a hard and fast rule may do more harm than good. DonH let weeds grow. Take the appearance of each weed as a danger signal of a raid on your plant food. DbnH let cracks form. They are holes through which valuable moisture escapes. Don^t cultivate when your ground is wet enough to form clods. Clods tie up plant food so that the corn roots can not use it. Don^t waste cultivation. Cultivation may be a waste of time or may be actually injurious when your soil is in good condition — moist below, dry and light on the surface, free from weeds. Failure to cultivate promptly and prevent the soil from becoming cracked, hard, or weedy may mean a material lessening of your corn yield. WATCH YOUR PLANTS Their progress determines how you should cultivate. While the plants are small cultivate as deeply as the condition of the soil makes necessary. Deep cultivation then is desirable if your seed bed was not well prepared before planting. Who would attempt to grow good corn in a small flower pot? Remember that hard ground can confine roots as effectually as pottery. Get your soil into open condition so that the corn roots can reach out for food. After the plants become a foot high shallow cultiva- tion only should be given. The roots have spread out close under the surface of the soil and would be injured by deep cultivation. Never cultivate deeply close to corn plants after they are a foot high. Such cultivation will break feeding roots and cause injury to the plants. PRODUCE THE LARGEST YIELD POSSIBLE Don't be satisfied with less than 50 bushels of corn per acre The average yield of corn per acre in the United States is about 27 bushels. With good seedy fair soil, and careful, timely cultiva- tion, we can and should double this average.
